thence downwardly. It isalso clear that the walls 27, 28 overlap the wall 29 and are inserted between the walls 26, 2 9. The passage portion 38 terminates at its lower end in downwardly and outwardly peripherallydischarging nozzles 39 which are gradually reduced outwardly and which are arranged to discharge in a direction opposite to the direction of rotation so that centrifugal ac tion will to a greater or less degree tend to cause flow of the ore through the machine. Under some conditions it may be advisable to extend the nozzles 39 to increase the centrifugal discharging action and for that purpose nozzle extensions 40 may be provided as shown in the drawings, said nozzle extensions being fastened by cap screws 41 or equivalent to the outer wall of the shell 19 so that the bores of the nozzles and nozzle extensions aline with one another. It is understood that this machine will function without the nozzle extensions 40 if so desired.

The passage portion 20 is of slightly less diameter at its lower end than at its upper end and the passage portion 23 is of slightly less diameter at its upper end than at its lower end. Likewise the passage portion 38 is of less diameter at its upper end than at its lower end. This is for maximizing conservation of the mercury and facilitating the flow of the metalliferous ore through the passage.

The lower end of the shaft 34 is supported in a step-bearing 41 which is fastened by cap screws 42 or equivalent to the base member 1. The shaft 34 is provided with a pulley 43 just above thestep-bearing 41, and the upper portion of the shaft is journaled just be neath the collar 33 at 44 in a tubular upwardly extending portion 45 of the base, there being a clearance between said tubular member and the tubular member At the lowest point in the passage portion 22 is an inwardly reduced clean-out port or ports 46 in which fits a tapered plug or plugs 47 having a head or heads 48 suitable for turning by a wrench, not shown. The plug is provlded with an inwardly extending in ternally threaded sleeve 49 adapted to en gage the externally screw-threaded reduced portion 50 of a nipple which also comprises an enlarged externally screwthreaded por tion 51. The bore of the nipple forms the outer portion of the port 46.

In practice, the desired amount of mercury will be run into the passage portion 20 of the machine and power will be applied to the pulley 43 to rotate the collar 33 and the.

parts connected with said collar, thus causing the mercury, not shown, to form an annular body in the passage portion 20 between the shoulders 24, 25. The crushed metalliferous ore to be amalgamated will be introduced under suitable pressure through" the intake member 8 into the passage portion flow through the passage portions 22, 23 and 38 to the nozzles 39 and will be forced outwardly from said nozzles into the helical passage3 of the base '1. The force of discharge of the material from the nozzles 39 is sufficient to cause the material to flow from the helical passage 3 through the discharge opening 4. r

When it becomes necessary or-desirable to remove the amalgam from the machine, operation of the machine will be stopped,

whereupon the amalgam will flow into the lower portions of the passage portions 20 and 22. Pipes indicated in broken lines at a Fig. 1, will be screw-threaded onto the en- 'larged portion of the nipples 51, and a suitable wrench, not shown, will be inserted in f the pipes to engage the heads 48 of the plugs.

Turning of the wrench will unscrew the plugs and the amalgam will flow through the ports 46 into the pipes a andthence into a suitable container, not'shown, placed at the discharge ends of 'saidpipesa.

It is noted that the centrifugal action aiding in the discharge of the tailings from the shell is of advantage for the reason that the lower end of the passage in the shell is thereby cleared of the tailings so that the pressure of the incoming ore will not cause the particles of the ore'to become too closely packed in the passage. It is readily seen that owing to the centrifugal action tending to keep clear the lower end of the passage the pressure required to force the ore through the-machine is less on a given character of ore than if the centrifugal discharging action were not provided for. By having less pressures, it is clear that leakage of From the foregoing it is clear that the centrifugal action of the tailings in the discharge end of the shell passage is suflicient to prevent clogging of the passage even though theforce of the ore feed at the feed end of the passage be insufficient of itself to cause the ore to flow through the lira-- chine at a desirable rate of speed. The advantage of this is thatpressures inside of the shell may be minimized so as to minimize leakage past the packing 11, and through the joint of the various sections of I 9 mm;
